Close to human perception and stable color sensing is an ubiquitous problem found in numerous disciplinces, e. g. , in machine vision for classification and recognition or in general intelligent systems, for instance for intelligent illumination systems in home or working environments. In particular for systems and applications of Ambient Intelligenc

e small, flexible, and preferably wireless modules and networks of such sensor modules are required. In this project, a wireless color sensor was developed based on MAZeT color sensors (MCS3AT, MCS3BT, MCSi) and MICA dot modules. An additional dot extension board and appropriate software was designed and implemented. The system was validated for typical color classification tasks, e. g. , for medical laboratory object recognition. Future work will consider the use of multiple wireless color-sensor modules as a component for intelligent illumination systems, both for machine vision as well as for home applications. The information conveyed by color is of significant interest in numerous application fields, ranging from machine vision applications for quality assurance as well as object segmentation, classification and general recognition tasks of intelligent engineering systems. For instance, the classification of medical objects displayed below, which has been pursued in a separate project activity, shows clearly the issue and benefit of color for the recognition process. For corresponding sensing activities, in particular, the stability or color constancy of the sensing element and module is decisive for the overall system performance. A common problem in machine vision is the aging of the applied light sources, which lead to a gradual degradation of system performance. A similar problem can arise for color sensors with...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
